大家好，我是约翰•麦克罗伊，欢迎收看Autoline 中国，我们的节目将为您呈现汽车领域最重要最前沿的行业新技术。
本田和松下测试可拆卸电池
本田和松下正在联手测试带有可更换电池的电动摩托车。他们将在印度尼西亚的几十个地点安装充电站，为本田的移动电源组充电。您只需在需要时取其中一个充满电的电池即可。这是可插拔电池的完美应用，因为它们足够小，可以将一堆电池存放在充电站并轻松更换。特斯拉和一家名为Better Place的公司尝试在汽车上使用可更换电池，但由于其过于复杂，尽管做了很多努力，但始终没能实现。
全新缝合处理
将汽车内部缝合在一起并非易事，我相信我们大多数人之前已经看过一两针缝合失误的情况。但供应商恩坦华正在努力确保失误不再发生。它开发了一种新的拼接工艺，通过使用激光来扫描针迹，并在必要时调整机器人的编程路径。它甚至可以在组件正在被缝合时进行动态操作。Inteva表示，新工艺将循环周期缩短了20-30％，并将用于新款雪佛兰Silverado和GMC Sierra皮卡的仪表板上。
接下来……看看带有极端悬挂系统的军用车辆。
沃尔沃的船舶自主技术
我们已经向您展示了沃尔沃汽车和商用卡车部件的自动驾驶技术，现在沃尔沃集团其他方面也正在展示其自动化技术。生产船用车辆的沃尔沃遍达（Volvo Penta）在一艘21米长的游艇上展示其自动对接技术。该系统使用位于船和码头上的GPS和传感器来帮助船只自动“停放”。虽然这看起来并不那么震撼，但对接过程可能变得很困难，因此从这种技术中消除对接的压力是一个很大的帮助。该公司的目标是在2020年推出这项技术，但不仅适用于新船，它还在开发一种可以反向改装成旧型号的版本。
悬架行驶到极致！
在过去，使军用车辆更安全就意味着承载更多的装甲。但是国防高级研究计划局（DARPA）有一个旨在提高生存能力而不增加更多装甲的计划。该计划的一部分包括由Pratt＆Miller开发的极端行驶悬挂系统。当我说极端时，这是名副其实的极端。它可以向上移动107厘米，向下移动76厘米，总共可以移动1.8米。这将允许车辆在崎岖的地形上以高速行驶，而不会使乘客感到颠簸过度，或者在陡峭的山坡上行驶而不用担心翻倒。令人感到神奇惊讶的是车辆的驾驶室几乎在行驶过程中没有移动。
下一步：特斯拉如何通过巧妙的电子工程降低汽车成本。
TESLA如何降低模型3的成本
Munro and Associates是一家进行竞争分析的公司，它最近全面分析特斯拉模型3后得出结论，该车可以产生超过30％的毛利润率。这是根据平均每辆特斯拉模型3，在美国约为50,000美元的价格。
但Munro表示，即使是基础35,000美元的型号也可以产生两位数的利润率。
关键是特斯拉将所有电子设备整合到许多主板中，并使这些芯片和集成电路具有双重功能。因此，特斯拉不是将所有不同组件中的分立芯片和IC分散在汽车周围，而是将它们放在一个位置。这样，它需要更少的芯片和集成电路，这就大大降低了成本。
希望您喜欢本期内容。那么本期Autoline中国的节目到这里就结束了。感谢您的收看。
Hello, I’m John McElroy, welcome to Autoline China, the show that covers some of the most important new technologies in the automotive industry.
HONDA & PANASONIC TEST SWAPPABLE BATTERIES
Honda and Panasonic are teaming up to test electric motorcycles with swappable batteries. They’ll install charging stations at several dozen locations in Indonesia to charge Honda’s Mobile Power Pack. You just grab one of those fully-charged ones anytime you need it. This is a perfect application of swappable batteries because they’re small enough to store a bunch of them at the charging stations and swap them out easily. Tesla and a company called Better Place tried swappable batteries with cars, but those efforts never really caught on because it’s just too complicated.
NEW STITCHING PROCESS
Stitching together the interior of a car is not an easy task and I’m sure most of us have seen a stitch or two out of place before. But supplier Inteva is working to make sure that never happens again. It developed a new stitching process that uses lasers to scan the stitch and adjust the programmed path of the robot if it needs to. It’s even able to do this on the fly, as the component is being stitched. Inteva says the new process reduces cycle time by 20-30% and will be used on the instrument panel for the new Chevrolet Silverado and GMC Sierra pickup trucks.
Still to come…a look at a military vehicle with an extreme suspension system.
VOLVO’S AUTONOMOUS TECHNOLOGY FOR BOATS
We’ve shown you self-driving technology from Volvo’s car and commercial truck units and now another part of the Volvo Group is showing off autonomous technology. Volvo Penta, which makes marine vehicles, just demonstrated self-docking technology in a 21-meter yacht. The system uses GPS and sensors, located on both the boat and the dock, to automatically “park” it. While it doesn’t look all that impressive, docking can be difficult, so to take the stress out of that maneuver is a big help. The company is aiming to launch the technology in 2020 but not just for new boats, it’s also developing a version that can be retrofitted into older models.
SUSPENSION TRAVEL, TO THE EXTREME!
In the past, making a military vehicle safer meant slapping on more armor. But the Defense Advanced Research Projects Agency or DARPA has a program that aims to improve survivability without adding more armor. Part of that initiative includes an extreme travel suspension system developed by Pratt & Miller. And when I say extreme, I mean extreme. It’s able to move 107 centimeters up and 76 centimeters down for a total of 1.8 meters of travel. This would allow vehicles to travel at high rates of speed over rough terrain, without roughing the passengers up too much or drive on the side of a steep hill without fear of tipping over. And it’s pretty amazing how the cab of the vehicle barely seems to move.
Coming up next: How Tesla is reducing the cost of its cars with clever electronics engineering.
HOW TESLA REDUCED THE COST OF THE MODEL 3
Munro and Associates is the name of a company that does competitive analysis and it recently tore down a Tesla Model 3. It concluded the car can generate gross profit margins greater than 30%. That’s for the average Model 3 which is going for about $50,000 in the United States
But Munro says even the base $35,000 model can generate double digit profit margins.
The key is that Tesla consolidated all the electronics into a number of motherboards, and has those chips and integrated circuits doing double duty. So instead of having discrete chips and ICs in all the different components scattered around a car, Tesla puts them all in one spot. That way it needs fewer chips and integrated circuits, and that greatly reduces the cost.
We thought you’d enjoy that information. But with that we wrap up this episode of Autoline China, thanks for watching.
